I have a question about Blueprint Interface. That is, after I create a function in interface blueprint, when I try to call that function in my actor blueprint, two identical functions will appear, one is （message), the other is ordinary function. I already know that the (message) function is used to send messages to the blueprint we want to communicate with, but what is that another function with the same name used for?
It is explained here : Calling Interface Functions on Other Blueprints
